SLUICE-VALVE Specification of Letters Patent.

Patented March 80, 1909.

Application filed. April 2&, 1908. Serial No. 428,993.

To all whom it may concern:

Be it known that I, FRANZ Snirrnn'r, a subject ofthe King of Prussia, German Emperor, and resident of 154C Koepenickerstrasse, Berlin, Kingdom of Prussia, German Empire, have invented new and useful Improvements in Sluice-Valves, of which the following is an exact specification.

This invention relates to sluice valves of the kind in which the valve is composed of two closing parts moved radially and then axially with regard to their seats by means of a radially movable wedge interposed between the two parts.

The present invention consists in providing positive means in the form of a movable clutch piece for opening as well as closing the valve, said movable clutch being arranged to be taken out of operation after the radial movement and when the closing partsiof the valve are arranged opposite their cooperating seats. In this position the further movement of the wedge presses the closing parts against their cooperating seats.

A further object of the present invention is to provide in combination with the moving clutch mentioned above an improved ball and socket arrangement by which the closing parts are brought securely against their seats independently of inexactitudes in the wedge surfaces.

In the accompanying drawings the invention. is illustrated in two modifications by way of example.

Figure 1 shows a vertical cross section through a sluice valve according to the present invention, Fig. 2 is a section at right angles to the section shown in Fig. 1, one of the closing members of the valve being removed in Fig. 2 in order to reveal the sliding clutch device according to the present invention, Fig. 3 is a partial view similar to Fig. 2 showing the parts in the position which they occupy when the valve is opened, Fig. 4 is a partial cross section similar to Fig. 1 and illustrates a modified form of sluice valve in which the closing parts are adapted to conform to the plane of their co-acting seats independently of the wedge surfaces, Fig. 5 is a separate view of one of the closing members of the valve, Fig. 6 is a detail showing the socket of the ball joint part employed in Fig. 4.

In carrying the invention into efl'ect ac cording to the form illustrated in Fig. 1 the casing (z of the valve is of ordinary shape and provided with suitable flanges b and (1. The valve is composed of closing parts (Z and (1 adapted to be pressed against their courting seats (1' and c by means of a wedge j' which may be moved upward and d ownward by means of a screw u in the well known manner. Otherwise the construction of the operating gear for the wedge f is of ordinary vided with two sloping surfaces 9 and 21.

On the closing members (5 and 0 there are formed projections ll and i by which as hereinafter described the closing members (i and c are positively coupled to the moving wedge f during downward movement of the same. During upward movement of the wedge the slide g engages with the parts '11 and w on the closing members (Z and 0 respectively.

The operation of this device is as follows: From the closed position shown in Fig. 1 the wedge by the turning of the screw u is first raised without raising the closing parts of the valves (Z and c. After the wedge f has risen for some little distance the slide 9 coimnences to bear against the projections o and 10 on the closing members (Z and c and further as the nose piece or lies against the raised portion of the projection 0 the slide g is in the position shown in Fig. 2. During upward motion of the wedge in company with the closing parts (Z and a the nose or rounded portion it comes against the sloping edge 9 of the cam projection 0 and thereby the slide g or coupling member is pushed toward the left in Fig. 2 and into the position shown in Fig. 3. In this position the slide g lies over the projections h and (I on the closing members (Z and 6 respectively.

In this way when the wedge is again moved downward the slide or coupling member 9 engages with the projections IL and i and thereby positively moves the closing members downward radially with regard to the through going passage in the valve casing while at the same time preventing the wedge f causing jamming of the parts before the closing pieces (Z and e descend into proper position opposite their I (Z and e to accommodate themselves directly seats. During the descent of the pieces (Z and c that is during the radia movement of these pieces with regard to the throughgoing passage in the valve casing the nose piece m comes a ainst the sloping edge 7) of the cam 0 at l more v the sliding coupling member g is again w endrawn from en agement with the parts 1 and '2 and the further downward motion of the wedge 7' which is necessary for the purpose of tightening the parts (Z and e is thereby permitted.

In Fig. a there is illustrated a form of this invention in which the closing parts (Z and 6 may adjust themselves to the planes of their respective co-acting closing seats (Z and 0 independently of the wedge surfaces. In this form of this invention the sliding coupling member 9 is arranged as described with reference to Figs. 1-8 and requires no further description. On the closing memher 6 there is formed a convex projection 05 on which there bears a concave bearing surface formed on a bearing plate 9 The bearing plate y is provided with a sleeve y" passing over a sleeve (Z on the closing part rZ. A spring a is provided between the parts g and (Z for the purpose of preventing rattling. The bearing piece 3 is provided with-wedge bearing surfaces y adapted to coaot with the wedge formed surfaces of the wedge f. The wedge f in this case is not formed in one piece with the actuating rod f but is forked shaped at its upper end which is coupled to the eye on the end of the spindle j by means of a pin f. The pin f is fixed to the wedge f and moves in a slot on the eye at the end of the actuating rod f as can be seen in the drawing. It will be seen by this arrangement that the wedge f can accommodate itself somewhat to the position of the wedge surfaces. By means of this device it will be seen that when the sliding piece 9 has been liberated from the projections 72 and i as described with reference to Figs. l3 the downward motion of the wedge will press the closing parts (Z and 6 against their co-acting seats (Z and e and allow at the same time these closing plates to the planes in which these co-acting seats lie. Thus any inexactitude will be taken up by the intermediate piece y and a correspondingly modified position of the wedge f.

I claim:

1. A sluice valve having in combination with a valve casing having valve seats therein, two closing parts adapted to be moved radially and axially with regard to their ea ts, a wedge interposed between these clos ing parts and provided witn a guide slot there'n, a sliding clutch piece guided to slide in said slot in the wedge, projecting lugs on the closing parts with which said sliding clutch is adapted to engage, a lever pivotally carried by the wedge and articulated to said sliding clutch piece, and a fixed cam adapted to engage said lever to move said clutch piece in out of engagement with the closing parts when said parts are axially opposite their seats, substantially as described.

2. A. sluice valve having in combination with a valve casing having valve seats therein, closing parts adapted to be moved radially and axially with regard to said seats, a wedge arranged between said closing parts, a bearing plate having a spherical socket thereon, interposed between the wedge and one of the closing parts, a ball shaped projecting bearing on the closing part, with which said socket engages, a sliding clutch iece guided in a slot on the wedge, pro jecting lugs on the closing parts with which said slide is adapted to engage, a pivoted lever arranged at one side of the wedge, a link connecting said lever to the clutch slide, and a cam projection on the valve casing with which said lever is adapted to engage to move the sliding clutch piece in and out of engagen'ient with the projecting lugs on the closing parts, substantially as described.

In witness whereof, l have hereunto set my hand in the presence of two witnesses.
